Data - Employment of a 1D model to study the intramolecular OH torsion of phenols

To reproduce the experimental splittings, we developed a numerical 1D model to solve the rovibrational problem. In this work, we apply the model using the dihedral angle between the planes defined by (i) the C(phen)—OH group and (ii) the phenyl ring as the leading coordinate. This represents a periodic intramolecular motion, whose periodicity is influenced by the identities and positions of the substituents on the phenyl ring.
